Abstract
The wall conductive flux in gas for a turbulent and homogeneous flow in a channel is directly deduced from a laser beam deflection technique. The main advantage of this method is the elimination of the radiative flux contribution. The beam deflection is due to the refractive index gradient field induced by a temperature gradient field at constant pressure. Experimental data are treated by using a parameter estimation method. Experimental fluxes associated with Reynolds number based on the hydraulic diameter in the range 1.75 × 10 4−3.5 × 10 4 and a temperature gradient in the range 60–120 K mm −1 agree with the results of a two-dimensional turbulence model when taking into account all uncertainty causes.
